Withdrawals after 65 are taxed as ordinary income, not at a special rate

Once you turn 65, money you withdraw from a traditional 401k is taxed as regular income at whatever tax bracket you fall into that year. There is no separate "senior tax rate" or reduction in the tax rate itself. A withdrawal of $10,000 is taxed the same way whether you are 65 or 45 — the difference is that at 65 you may have other income sources (Social Security, pensions, part-time work) that push you into a higher bracket.

The tax rate depends on your total income for the year, your filing status, and the current tax brackets set by the IRS. If you are single and your total income is $47,000 in 2024, you pay the tax rate for that bracket. If your total income is $100,000, you pay a higher rate on the income above the first bracket threshold. Your age does not change the brackets themselves.

Roth 401k withdrawals work differently: if you have held the account for at least five years and are 59½ or older, withdrawals are tax-free. If you withdraw before meeting both conditions, you owe tax on the earnings portion (though not on your own contributions).

Key Takeaways

  • Traditional 401k withdrawals after 65 are taxed as ordinary income at your marginal tax rate, which depends on your total income that year, not your age.
  • Roth 401k withdrawals are tax-free after age 59½ if the account has been open for at least five years; otherwise earnings are taxed.
  • Required Minimum Distributions (RMDs) begin at age 73 and are taxed as ordinary income whether you need the money or not.
  • Taking withdrawals before age 59½ triggers a 10 percent early withdrawal penalty on top of ordinary income tax, with limited exceptions.
  • Your tax bracket can shift upward if you have Social Security, pension income, or other sources alongside 401k withdrawals.

How your tax bracket is calculated when you withdraw

Your 401k withdrawal is added to all other income you received that year — wages, self-employment income, Social Security, pension payments, interest, dividends, rental income. The IRS adds these together to find your total income, then applies the tax brackets for your filing status (single, married filing jointly, head of household, etc.) to determine how much you owe.

This matters because withdrawals can push you into a higher bracket. If you are single and earn $45,000 in pension income, a $20,000 401k withdrawal brings your total to $65,000. The first portion of that withdrawal may be taxed at your existing rate, but the amount that crosses into the next bracket is taxed at the higher rate. This is called "bracket creep" and is one reason some people spread withdrawals across multiple years.

Social Security income complicates this further. Up to 85 percent of your Social Security benefits can be counted as taxable income if your total income (including half your Social Security) exceeds certain thresholds. A large 401k withdrawal can trigger taxation of Social Security benefits you thought were tax-free.

Required Minimum Distributions starting at age 73

At age 73, the IRS requires you to withdraw a minimum amount from your traditional 401k each year, whether you need the money or not. This amount is calculated by dividing your account balance by a life expectancy factor published by the IRS. The withdrawal is taxed as ordinary income.

If you do not take the full RMD, you owe a penalty of 25 percent of the shortfall (reduced to 10 percent if you correct it within two years). This is one of the steepest penalties in the tax code. Some people withdraw more than the RMD to manage their tax bracket or to cover expenses; others withdraw exactly the minimum to reduce their tax bill.

Roth 401ks are subject to RMDs as well, though you can roll a Roth 401k into a Roth IRA to avoid RMDs entirely. Traditional IRAs also have RMDs at 73, but Roth IRAs do not.

The 10 percent early withdrawal penalty and its exceptions

If you withdraw from a traditional 401k before age 59½, you owe a 10 percent penalty on top of ordinary income tax. At 65, you are past this threshold, so the penalty does not apply to you. However, if you separated from your employer at 55 or later, you may have been able to withdraw penalty-free under the "Rule of 55" — this exception does not extend past age 59½, but withdrawals taken under it between 55 and 59½ remain penalty-free.

Other exceptions to the early withdrawal penalty include disability, medical expenses exceeding 7.5 percent of adjusted gross income, and substantially equal periodic payments (SEPP). Once you are 65, the penalty is no longer a concern for new withdrawals, but it may have affected withdrawals you took earlier.

State income tax on 401k withdrawals

Federal income tax is only part of the picture. Most states tax 401k withdrawals as ordinary income as well. Nine states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire for dividends and interest only). The remaining states tax withdrawals at rates ranging from roughly 3 percent to 13 percent, depending on the state and your income level.

Some states offer partial exemptions for retirement income. Illinois, Mississippi, and Pennsylvania exempt 401k and IRA withdrawals entirely. Other states exempt only pension income or only Social Security. If you are considering moving in retirement, the state tax treatment of 401k withdrawals can be a significant factor in your decision.

Withholding and estimated tax payments

When you withdraw from a 401k, your employer (or the plan administrator) can withhold federal income tax directly from the payment. The default withholding rate is 20 percent if you take a lump sum, though you can request a different amount. This withholding is not a tax; it is a prepayment toward your tax bill.

If your withholding is too low, you may owe additional tax when you file your return. If it is too high, you get a refund. Some people adjust their withholding each year based on their total income and expected tax bill. Others make quarterly estimated tax payments if they have income sources without withholding (like rental income or a pension that does not withhold).

The key is to withhold enough throughout the year to avoid owing a large bill in April or facing underpayment penalties. The IRS charges interest on underpayment, even if you ultimately owe no tax.

Frequently Asked Questions

Do I pay less tax on 401k withdrawals after 65 than before?

No. The tax rate on withdrawals is the same at 65 as it was at 45 — it depends on your income bracket, not your age. What changes is that you may have other income sources (Social Security, pensions) that affect your total income and bracket. You also no longer face the 10 percent early withdrawal penalty if you take money out.

What if I withdraw only what I need and leave the rest in the account?

You can withdraw any amount you want, but at age 73 you must withdraw at least the RMD or face a 25 percent penalty on the shortfall. Withdrawals before 73 are optional and taxed as ordinary income. Leaving money in the account does not reduce your tax bill — only the amount you actually withdraw is taxed.

How much will my 401k withdrawal push me into a higher tax bracket?

That depends on your filing status and total income. For 2024, if you are single, the 22 percent bracket ends at $47,150 and the 24 percent bracket begins there. A $10,000 withdrawal might be entirely in the 22 percent bracket, or it might cross into the 24 percent bracket, depending on your other income. Use the IRS tax tables or a tax calculator to estimate your bracket.

Can I avoid taxes by taking withdrawals slowly over many years?

You can reduce your tax bill by spreading withdrawals across years to stay in a lower bracket, but you cannot avoid taxes entirely on traditional 401k money — it was never taxed when you contributed it, so the IRS will tax it when you withdraw it. Roth 401k withdrawals are tax-free if you meet the age and holding-period requirements.

What happens to my 401k if I die before taking all the money out?

Your beneficiaries inherit the account and must withdraw it within ten years (with some exceptions for spouses and disabled beneficiaries). The withdrawals are taxed as ordinary income to them. The account itself is not subject to estate tax, but the income tax liability passes to whoever inherits it.
